Methadone Overdose | Methadone Overdose Signs, Symptoms & Treatment

Table of Contents

The opioid medication,methadone, is used for several purposes in the treatment of opioid addiction across the United States. Like other prescriptions, methadone is typically safe and effective when used as prescribed.

Methadone may be used to ease pain and withdrawal symptomsassociated with opioid use. This process is commonly referred to as detoxification, ordetoxfor short. Detox is a grueling process for those suffering from substance use disorders. Methadone is used as a safer alternative to quitting cold turkey. In its entirety, the process may take anywhere from three days to upwards of20 weeks.

Additionally, many patients are prescribed the drug as a means to maintain their progress in opioid recovery, while also reducing their dependence on these detrimental substances.

Methadone may be used for maintenance treatment, sometimes lasting several years. Inmethadone maintenance therapy, the goal is to reduce opioid use by users who have struggled with abstinence in the past. This can sometimes be a lifelong battle. Many clinics and rehabilitation centers also offer methadone reduction programs focused on achieving complete opioid recovery.

Those with an addiction toheroinhave the most to gain from methadone treatment. The drug is used to block heroin cravings, with effects lasting much longer than heroin itself.

Unfortunately, methadone treatment can lead to a troubling result:methadone addiction. Methadone misuse comes with the potential of a lethal overdose, so, it’s essential to distinguish the signs and symptoms of overdosing on this medication.

Methadone Overdose Symptoms

In 2019, methadone was attributed to about 4% ofopioid fatalities, so the rate is relatively low compared to other opioids. About 3,000 overdose deaths occurred that year due to methadone.

Methadone overdose often occurs because the drug remains in the body for a long period of time. Even after several hours have passed and the pain relief has subsided,methadone is not clear of the body. There is a reason why those in treatment programs are only given one dose per day. Accumulation of dose after dose can have deadly consequences.

Overdose symptoms should never be overlooked or disregarded. Different areas of the body may exhibit different symptoms:

  • Gastrointestinal System: The stomach and surrounding muscle structures are susceptible to a number of complications due to a methadone overdose. These may include spasms, vomiting, constipation and more.
  • Vascular and Respiratory System: The lungs are a primary attack point for methadone overdose. Labored breathing, slow breathing and a tight chest can occur.
  • Central Nervous System: Becoming confused or disoriented is not out of the question with a methadone overdose. On top of this, one may experience drowsiness or fatigue.

Signs of a Methadone Overdose

If you come across someone demonstrating signs of a methadone overdose, seek medical attention right away. Signs of overdose mayinclude:

  • Low blood pressure and a weak pulse
  • Constricted or pinpoint pupils
  • Body spasms at irregular intervals
  • Dizziness or disoriented behavior
  • Cold, clammy skin
  • Blue lips and fingernails
  • Absence of breathing or consciousness

If an individual is able to speak, they may attempt to talk you out of taking them to the hospital. They may insinuate that they feel no pain whatsoever. This may be the residual effects of the methadone masking their true discomfort. Overdose signs may present themselves immediately or shortly after ingesting methadone. Do not sit idly by; always react to the threat of an overdose in others.

Methadone Overdose (mg)

Methadone, like other opioids, has a large range in terms of lethal dosage because of the body’s rapid ability to increase tolerance. Due to increased tolerance, consistent opioid users may be able to get away with using more methadone at a time.

Alcoholis known to aggravate the situation and lower the amount of methadone it takes to produce a lethal overdose. The two substances should not be mixed under any circumstances. The same can be said for combining methadone and benzodiazepine.

As bizarre as it may sound, some experts also suggest that methadone patients avoid drinkinggrapefruit juicewhile on the drug. There appears to be a slight correlation between an increased methadone bioavailability — the rate at which the substance is absorbed by the body — and consumption of the beverage.

Methadone Overdose Treatment

Getting someone who may be experiencing a methadone overdose to the nearest emergency room is priority number one. Overdosing on methadone means that a large amount of the medication is in the system and immediate procedures must take place to remove it.

Depending on the severity, physicians may choose to use activated charcoal to neutralize the drug in the stomach or perform gastric lavage to remove stomach contents entirely. Victims will then be put on a regimen of IV fluids and monitored until overdose symptoms dissipate.

Addiction may feel like an uphill battle, but recovery is possible with the right treatment program.
